Sažetak
The cyclic voltammetry of red PbO, α-PbO2, β-PbO2 and BaPbO3 was studied with two different types of electrodes in acidic and alkaline media. In one case, microcrystalline particles of lead oxides were mechanically immobilized on the surface of paraffin-impregnated graphite rod electrodes (PIGE), while in the other case, lead oxides were added to a paste of graphite and silicone oil. The overall behaviour of lead oxides in both electrodes is very similar to the well-known behaviour of electrodes made of lead oxide powders.
The results show that the binder does not effect the overall electro-chemistry of lead oxides. Moreover, the electrochemical reactions are more reversible for the paste electrode than in the case of the PIGE.
